Feeling stuck in current job

Feeling pretty stuck in my current role and not sure how to move forward. I have a bit over a year of pretty solid IB experience at a good bank and then went to strategic finance role at a relatively well known large company. My current role has definitely been much better work-life balance and the culture / people are great, but it feels very slow and stagnant compared to the pace and progress in banking. I admittedly was not in a great place during banking and really wanted wlb but now feeling antsy about getting stuck in corporate at a relatively junior level. The work itself has also gotten less interesting over time due to the current economic climate focusing less on the market / growth strategy that I was interested in and into projects dealing more with nitty-gritty accounting level work focusing on operations and costs. I did really like the deal process and valuation work in banking and thought a higher level strategy type role would've been interesting but I do also miss some of the more pure technical finance application as well. I also really do enjoy following the markets which wasn't directly my role in banking obviously but is basically nonexistent in corporate.

In my position, I'm not sure what would make sense next. I'm pretty sure I wouldn't want to move to another corporate, even in a more M&A / technical role, as I think the pace still isn't quite the same as financial services. I am very young but it feels like many doors that I previously had in banking would be shut now. I've thought about going back to IB (not anytime soon in the current landscape) or trying to use my past banking experience for some sort of investing roles though currently being in a corporate role will definitely add a hurdle to making that switch. Obviously not MF/UMM PE but if there's any sort of LMM/MM PE or public investing roles still possible I would definitely be interested in that route. I am also hesitant about moving onto a third job and the implications there on my resume. I have thought about b-school but the cost makes me wary unless i have a very specific plan. I would greatly appreciate any advice or personal anecdotes on what others have done if in similar situations.
